Technology for producing magnesium oxide board through high-temperature curing

Abstract

The invention relates to a technology for producing a magnesium oxide board through high-temperature curing. The technology comprises the following steps: 1) preparing a gelling material of the magnesium oxide board; 2) compacting the gelling material to a board blank material; 3) sending the board blank material to a high-temperature drying room for high-temperature curing; the gelling material of the magnesium oxide board comprises a reinforcing material and the gelling material, wherein the gelling material is a mixture of magnesium oxide, magnesium sulfate and water, and the magnesium sulfate is a reaction promoter of magnesium oxide. The technology has the beneficial effects that 1) magnesium sulfate is employed for substituting magnesium chloride in the prior art, low-temperature curing is possibly changed to high-temperature curing, the curing time is greatly shortened, supporting plate running time is greatly shortened, curing area is reduced, and the production efficiency is increased; 2) drying room temperature is controllable, the drying room has insulation function, under prerequisite that the maximum utilization rate of energy is increased, the magnesium oxide board is efficiently produced; and 3) a rolling roller group is employed, and the magnesium oxide board is efficiently produced.

Description

technical field [0001] The invention relates to a production process of a high-temperature maintenance glass magnesium board. Background technique [0002] The use of magnesium oxychloride cement to produce glass magnesium boards (hereinafter referred to as glass magnesium boards) has a history of more than 20 years. Magnesium oxychloride cement uses magnesium oxide, magnesium chloride, and water as the cementitious material. In 1993, the magnesium oxychloride cement board rolling mill appeared. The production process of the glass magnesium flat board is to mix magnesium oxide, magnesium chloride, water and wood flour and other materials into a gel through multiple groups of rolling mills, and spread it on the pallet according to the required thickness. And press it into a plate blank. After the plate blank is solidified and formed on the supporting plate, the supporting plate is removed, and the burr is cut to become a glass magnesium plate. Due to the high heat of hydrat...

AI Technical Summary

Problems solved by technology

This kind of production process takes a long time to turn the pallets, requires a larger area of ​​maintenance room, and the production efficiency is low

As the demand for glass magnesium boards increases, the problems of long maintenance time and low production efficiency become more prominent
